Hello @naveenparmuwal,
Thank you for reaching out to us!
It might be an issue caused by a plugin or your theme.
I recommend installing this plugin: https://ww.wp.xz.cn/plugins/health-check/
After you install and activate the above plugin it has a Troubleshooting mode which allows you to have a vanilla WordPress session, where all plugins are disabled, and a default theme is used, but only for your user – your visitors will still see the normal website.
Go to its troubleshoot mode and only activate Simple Custom Post Order and see if it works correctly with a default WordPress theme (Twenty Nineteen for example) and no other plugins.
Please let me know how it goes and what you find!
Warm regards,
Beatrice.
